This morning, the ntsb is investigating what caused komo-tv's helicopter and its experienced crew to suddenly crash just after takeoff. We have report of a helicopter into the space needle down on the ground now. Cars involved on fire. Reporter: It was around 7:40 A.M.

Motorist jumped Ou of his & critically injured. The C wit body on fire. Reporter: Kille on impact, beloved veteran photographer bill Strothman and pilot Gary pfitzner. We just can't Bel he's gone. Station's windows. Anchors could barely contain themselves reporting the news that their friends were gone. We have reached the point here we can talk about the two this will be a very difficult time. It is a tough day already and this is even tougher.
